Keep the cultivator in safe working condi-
tion. Check all fasteners at frequent inter-
vals for proper tightness.
Repair / Adjustments Safety
After striking a foreign object, stop the en-
gine. Remove the wire from the spark plug,
and keep the wire away from the plug to
prevent accidental starting. Thoroughly in-
spect the cultivator for any damage, and
repair the damage before restarting and
operating it.
If cultivator should start to vibrate abnor-
mally, stop engine and check immediately
for the cause. Vibration is generally a warn-
ing of trouble.
Stop the engine whenever you leave the
operating position. Also, disconnect the
spark plug wire before unclogging the tines
and when making any repairs, adjust-
ments, or inspections.
When cleaning, repairing, or inspecting,

OPERATION
HOW TO USE THE CULTIVATOR
How To Stop The Cultivator
1. Release the throttle control to stop the
tines.
2. Move the ON/OFF switch, on the engine,
to the OFF position.
In this position, the depth stake, not the
wheels, will contact the ground.
For cultivation in heavy soil, use the
storage hole position.
For seed bed preparation, use one of
the middle holes.
4. Reinstall the clevis pin and hairpin.
How To Set The Depth Stake And
Wheels
The depth stake and wheels can be set with
the wheels down (transport and light cultiva-
tion) or with the wheels up (heavy cultiva-
tion). Position as follows:
1. Remove the hairpin and the clevis pin
from the depth stake (see Figure 4).
2. For transport or for light cultivation, posi-
tion the depth stake with the wheels
down.
For transport, use the upper hole
position.
For light cultivation, use one of the
middle holes.
3. For cultivation in heavy soil or for seed
bed preparation, position the depth
stake with the wheels up (see Figure 4).
How To Operate The Cultivator
1. Start the engine. See "How To Start The
Engine".
Firmly hold both handles. Squeeze the
throttle control until the tines begin to ro-
tate and the cultivator moves forward.
Maintain control and quickly squeeze the
throttle control against the grip.
Note: When tilling, always operate
with the throttle control against the
grip at a FAST engine speed.
3. To guide the cultivator, hold back on the
handles as the tines dig into the soil. The
faster the cultivator moves forward, the
more shallow it will till.

4. Avoid tilling soil that is too dry as it will
pulverize and produce a dust that will not
hold water. Also, tilling soil that is too wet
will be hard on the machine and produce
unsatisfactory clods.
5. Lowering the depth stake will slow the
cultivator and make it till deeper. Raising
the depth stake will allow it to move fast-
er and till more shallow. Just the oppo-
site is true for the wheels. Lowering the
wheels will make the cultivator move
faster and till more shallow. Raising the
wheels will make it till deeper. See "Row

How To Mix The Fuel Mixture
The two cycle engine, used on this cultivator,
requires a mixture of gasoline and oil for lu-
brication of the bearings and other moving
parts. The correct fuel mixture ratio is 24:1
(5.3 oz. oil per one gallon of gas see the
Fuel Mixture Chart). Gasoline and oil must
be pre mixed in a clean gasoline container.
Always use fresh, clean, unleaded gasoline.
Mix gasoline and oil as follows:
1. Pour one (1) U.S. quart of fresh, clean,
2. Add 5.3 ounces of clean, high quality,
fuel container. Do not smoke
when adding the fuel mixture to
the engine. When inside an enclosure,
do not fill the fuel tank. Before you add
the fuel mixture, stop the engine. Let the
engine cool for several minutes.

gallon size gasoline container.
two cycle oil to the gasoline container.
IMPORTANT: Do not use outboard mo-
tor oil or multi-viscosity oils,such as
10W-30 or 10W-40.
Install the fuel cap onto the gasoline con-
tainer. Vigorously shake the gasoline
container to mix the oil with the gasoline.
Add an additional three (3) U.S. quarts of
gasoline to the gallon container. Again
shake the gasoline container.
This completes the gasoline mixing pro-
cedure. The gasoline can now be added
to the fuel tank.

CULTIVATING TIPS
Tilling is digging in, turning over and
breaking up packed soil before planting.
Loose unpacked soil helps root growth.
Best tilling depth is 4 to 6 inches. A tiller
will also clear the soil of unwanted vege-
tation. The decomposition of this vegeta-
tion matter enriches the soil. Depending
on the climate (rainfall and wind), it may
be advisable to till the soil at the end of
the growing season to further condition
the soil.
Avoid tilling soil that is too dry as it will
pulverize and produce a dust that will not
hold water. Also, tilling soil that is too wet
will produce unsatisfactory clods.
Better growth will be obtained if an area
is tilled properly and used soon after till-
ing to preserve the moisture content.
The depth stake (on the back of the culti-
vator) serves a dual purpose. It helps
regulate the depth of the cut and also
acts as a brake to help the operator con-
trol the speed of the cultivator.
Lowering the depth stake will slow the
cultivator and make it till deeper. Raising
the depth stake will allow it to move fast-
er and till more shallow.
If the cultivator stops forward motion and
tries to dig deeper than necessary, move

Cultivating is loosening or digging
around growing plants which allows the
plants to flourish.
When using the cultivator to remove
weeds, it is best to cultivate no deeper
than 1 1/2 inches. Cultivating deeper will
only pull to the surface ungerminated
weed seeds.
When cultivating around plants or close
areas, you may want to remove the out-
side tines. See "Tine Replacement" in
